What should be done with --help in that case?
(In general, I'd expect such script not to use --help or --version at
all.)

Which other options should be processed when --script is given? Are
there any requirements for what command-line-args-left should have
when the script is loaded?
IOW, it is not clear to me what are the expectations in this use case.
Please take a look at how the command-line arguments are processed at
startup, in emacs.c and in startup.el, and make a more detailed
proposal. Then we could see if it's easy to implement without
potentially breaking anything.
